10 most bizarre allergies

Exercise

If someone tells you they’re allergic to exercise, there’s a slim chance they’re telling the truth. About 1,000 people suffer from exercise-induced anaphylaxis, a severe allergic reaction caused by physical exertion that may be related to eating certain foods or taking specific medications before exercise. Fatigue, itchy skin, hives and swelling of the neck, torso and extremities typically appear during or right after exercise, and symptoms can linger for hours. More severe reactions can include choking, vomiting, increased blood pressure and even death, so people with this allergy are advised to carry an epinephrine kit.
